(I'm not that knowledgeable about the in-depth tech oil stuff.)
The people on the oilguys site are a typical group of internet chatters...kinda like another site we know.
There are a few great ones on there - just takes time....
Me personally? Mobil 1 is fine as far as I can tell. I change it quite often due to frequent track use AND due to the fact that I can only get about 1/2 the oil out per oil change. Lots remains in the 3 oil coolers and lines. Plus I have a chitload of previously purchased M1 in the shop
